We compared examination of unstained and Gram-stained smears as methods of evaluating sputum quality. Of 100 slides examined, 96 (96%) were graded identically. Each discrepancy between methods was near the cutoff for specimen acceptability. We concluded that examination of unstained smears can provide an accurate, cost-effective sputum screening method.
我们比较了未染色涂片和革兰氏染色涂片检查作为评估痰液质量方法的效果。在检查的100张载玻片中,96张(96%)的分级相同。两种方法之间的每一处差异都接近标本可接受性的临界值。我们得出结论,未染色涂片检查可提供一种准确且经济高效的痰液筛查方法。
